    摘要： A coating system for Si-containing materials, particularly Si-based composites used to produce articles exposed to high temperatures. The coating system is a compositionally-graded thermal/environmental barrier coating (T/EBC) system that includes an intermediate layer containing yttria-stabilized hafnia (YSHf) and mullite, alumina and/or an aluminosilicate, which is used in combination with an inner layer between a Si-containing substrate and the intermediate layer and a thermal-insulating top coat overlying the intermediate layer. The intermediate layer provides environmental protection to the silicon-containing substrate, and has a coefficient of thermal expansion between that of the top coat and that of the inner layer so as to serve as a transition layer therebetween. The intermediate layer is particular well suited for use in combination with an inner layer of an alkaline earth metal aluminosilicate (such as BSAS) and a top coat formed of YSZ or YSHf.

    摘要： An article comprising a silicon-containing substrate, an environmental barrier coating (EBC) overlying the substrate, wherein the EBC comprises a higher metal silicate-containing outer barrier layer; and a corrosion resistant alumina/aluminate sealant for the higher metal silicate-containing outer barrier layer. A process is also provided for forming a corrosion resistant alumina/aluminate sealant layer over the higher metal silicate-containing outer barrier layer. Also provided is an alternative process for treating a porous higher metal silicate-containing outer barrier layer with a liquid composition comprising an corrosion resistant alumina/aluminate sealant precursor to infiltrate the porous higher metal silicate-containing outer barrier layer with the alumina/aluminate sealant precursor in an amount sufficient to provide, when converted to the corrosion resistant alumina/aluminate sealant, protection of the environmental barrier coating against environmental attack; and converting the infiltrated alumina/aluminate sealant precursor within the porous higher metal silicate-containing outer barrier layer to the corrosion resistant alumina/aluminate sealant.
